The hydraulic transmission of the embodiment has the working principle that:
when the input shaft rotates clockwise as a working rotation direction, when the input shaft 1 rotates clockwise at a rated rotation speed, the clutch A3 is connected with the clutch D8, the clutch B4, the clutch C6 and the clutch E10 are separated, the flow channel switch A5 and the flow channel switch C9 are opened, the flow channel switch B7 is closed, the small-diameter right-handed rotation driven impeller 14 and the left-handed rotation driven impeller 12 are locked, the input shaft 1 drives the pump impeller 16 to rotate, the pump impeller 16 pushes liquid to flow in the direction of the driven impeller, the liquid flows through the flow channel switch A5, then the liquid pushes the large-diameter right-handed rotation to rotate to the driven impeller 13, and the large-diameter right-handed rotation driven impeller 13 drives the output shaft 11 to rotate clockwise in an accelerated manner. The liquid pushes the large-diameter right to rotate to the driven impeller 13 and then flows through the flow channel switch C9, then flows to the pump wheel direction from the shell liquid circulation flow channel, is pushed by the pump wheel again, and circulates in this way.
When the output shaft 11 reaches a preset rotating speed, the clutch C6 is connected, the flow channel switch A5 is closed, the small-diameter right-handed rotation direction slave movable impeller 14 is unlocked, at the moment, liquid pushes the small-diameter right-handed rotation direction slave movable impeller 14 to drive the output shaft 11 to rotate clockwise, then the clutch D8 is separated, the flow channel switch B7 is opened, the large-diameter right-handed rotation direction slave impeller 13 is locked, and the small-diameter right-handed rotation direction slave movable impeller 14 drives the output shaft 11 to rotate clockwise in an accelerated manner.
When the output shaft 11 reaches a preset rotating speed, the clutch B4 is engaged, the input shaft 11 and the output shaft 1 are directly connected, the rotating speeds are synchronous, and the clutch A3 and the clutch C6 are separated.
